Decided to go ahead with my fat-tyre-26-inch Roadrat thing, so just working out the bits... Got the wheels, got the tyres, don't got the brakes (though I have suitable discs)
So. 5600 105 STIs, what to attach to the end? I don't expect it to see constant winter use etc but some longevity is good. BB5s? Will the new 105s work OK with my older levers?
